This project aims to make discoveries for modelling initiation, rate of progression and consequences of seepage induced internal erosion through soils which make up critical water retaining infrastructure like dams. It aims to achieve an understanding of how fundamental microstructural (particle and pore) properties governing erosion have the potential to destroy infrastructure. Major expected outcomes include experimental evidence of governing mechanics, theories which couple microstructure with erosion and models to describe the altered soil strength and stiffness. It aims to lead to increased safety and economic efficiencies in Australia where many tens of millions of dollars are spent each year to reduce risks associated with internal erosion.

该项目旨在发现渗流引起的土壤内部侵蚀的模拟启动、进展速度和后果，这些土壤构成了水坝等关键的保水基础设施。它的目的是了解控制侵蚀的基本微观结构（颗粒和孔隙）特性如何有可能破坏基础设施。主要预期成果包括控制力学的实验证据、将微观结构与侵蚀耦合的理论以及描述改变的土壤强度和刚度的模型。它旨在提高澳大利亚的安全性和经济效率，澳大利亚每年花费数千万美元来减少与内部侵蚀相关的风险。
